“It does take great maturity to understand that the opinion we are arguing for is merely the hypothesis we favor, necessarily imperfect, probably transitory, which only very limited minds can declare to be a certainty or a truth.”

“Truth is what is true, and it's not necessarily factual. Truth and fact are not the same thing. Truth does not contradict or deny facts, but it goes through and beyond facts. This is something that it is very difficult for some people to understand. Truth can be dangerous.”

“Neither can such a doctrine argue: it simply does not understand that other doctrines exist, can exist, it simply does not know how to imagine an opinion contrary to its own”

Is that infinity One, immanent and permanent, necessarily having substance, since He is infinite and if He lacked matter He would be limited, necessarily possessing intelligence since He is infinite and, lacking intelligence, He would be in that sense finite. Does this Infinity inspire in us the idea of essense, while to ourselves we can only attribute the idea of existence? In order words, is He not the whole of which we are but the part?”

“That our opinion does not coincide with that of others does not concern us in the least, for we are pleased only with that which pleases us, and not that with which others say we ought to be pleased.”
